Take the lung of a pork, a veal or a beef.
If you can get a heart, a kidney ... Cut all of this into cubes (size of a big dice).
If you like bacon, well that’s okay, put some bacon if you want.
Fry some onions in oil. Add the dice of heart, lung and kidney
Add some plants for the taste (thyme, bay leaf and parsley).
Add salt and pepper.
Pour in red wine and water.
Cook over low heat.

Attention heart and kidneys harden quickly, so you must add them at halfway.
You can use only lung, very cheap and warms up.
And that's good. Try it!
